Channel Vision 3102-104 Specs indicate it PASSES up THRU CATV Ch102 (660-666 MHz) and has a 4-channel wide Slope to the High Attenuation Region, which would start at about 666+24 = 690 MHz, which means it should be just what is needed for suppressing 4G LTE Cell Tower signals, unfortunately they don't indicate HOW MUCH ATTENUATION is provided (BOO, HISS)....but even 15-20 dB should be more than adequate:
